Is it possible to edit a sequence in PPro, use dynamic link to open it in AE, add effects to the sequence in a comp, and then use dynamic link in PPro to import the comp with the modified PPro sequence?
When I tried this there was no video in the comp that was linked back to PPro.
You dont need the last step.
1. Cut sequence in PrP.
2. Send sequence to AE via dynamic link
3. Create effects in AE.
Now, if you just toggle back to PrP. You have one dynamic linked segment that is the same length as your original PrP sequence.. You must render it in most cases to allow playback in PrP.
